摘要

The Phillips Laboratory Global Theoretical Ionospheric Model (GTIM) has formedthe basis for a series of investigative studies. First, a multiple ion version of the theoretical code has been developed that is based on the same numerical solution type, to help insure that 0+ densities are consistent with the existing one ion GTIM. Next, two new applications of the GTIM have been completed, in the study of wavelike disturbances in low latitude electric fields, demonstrating the resulting wavelike ionospheric effects, and in a study to determine the F region peak signatures that could be inferred from in Situ measurements made at DMSP altitudes. Finally, a system for ionospheric ray tracing is described that is based on a simple analytical profile model that can readily absorb real time information and whose ray tracing specification can be substantially improved with only minimal updates Work performed on neutral density studies has concentrated on the delineation and interpretation of longitudinal structures in SETA data. These include the 'longitude/UT' effect and longitudinal wave structures.
